David Disseldorp b454d754cb scsi: target/iblock: fix WRITE SAME zeroing 
commit 1d2ff149b2 upstream.

SBC4 specifies that WRITE SAME requests with the UNMAP bit set to zero
"shall perform the specified write operation to each LBA specified by the
command".  Commit 2237498f0b ("target/iblock: Convert WRITE_SAME to
blkdev_issue_zeroout") modified the iblock backend to call
blkdev_issue_zeroout() when handling WRITE SAME requests with UNMAP=0 and a
zero data segment.

The iblock blkdev_issue_zeroout() call incorrectly provides a flags
parameter of 0 (bool false), instead of BLKDEV_ZERO_NOUNMAP.  The bool
false parameter reflects the blkdev_issue_zeroout() API prior to commit
ee472d835c ("block: add a flags argument to (__)blkdev_issue_zeroout")
which was merged shortly before 2237498f0b.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
